It’s not just a letter that separates EPS (Expanded Polystyrene) and XPS (Extruded Polystyrene). When you’re selecting your polystyrene you need to evaluate the importance of key factors such as compressive strength, moisture retention, and insulating capability to ensure that you’re making the most cost-effective decision and material choice for the job.
A more common concern between these products is the compressive strength of the polystyrene, or the capability of your polystyrene to withstand size-reducing loads. It’s important to ensure that your material has adequate compressive strength to withstand day-to-day loads but going too high can mean a dramatic cost increase for very little – if any – gain. Confirming with your engineers and project managers the required compressive strength for the job will enable you to make an informed decision regarding which polystyrene to use.
